Here is some reading for anyone interested. This is the type I have done over the span of several years due to things being written about Albert and what John Glatt said about Princess Grace really ticked me off.

The Prince had every reason to be concerned. For any child of his would automatically be in line to the Monaco throne.
Page 234 of The Royal House of Monaco there is more saying Albert was scared etc.
However by taking the test he would be forced to acknowledge that she is his first born and heir to the throne. Despite my assurances I wanted nothing other than him to be a father to our daughter, his family feared an outsider would ultimately control the family.
Read the following and you will see why Tamara's words aren't factual it couldn't have happened. Law is something I understand and in my former work for over 5 years lost only 1 case due to my own error.
THE PRINCE
In the first chapter of this Constitution, it is laid down that the executive power is responsible to the supreme authority of the reigning Prince. The Constitution of 1962 also states that the succession to the Throne passes to the direct and legitimate descendants of the reigning Prince under the principle of primogeniture, male descendants taking precedence over female descendants of the same degree of kin. In the absence of legitimate descendants, an adopted child may succeed to the Throne. The Prince, however, can only exercise his powers if he has reached his majority, fixed at the age of 21. During his minority, power is exercised by a regency.
The Sovereign represents Monaco in its relations with foreign powers ; he signs and ratifies treaties.

Article 10
La succession au Trône, ouverte par suite de décès ou d'abdication, s'opère dans la descendance directe et légitime du Prince régnant, par ordre de primogéniture avec priorité masculine au même degré de parenté.
A défaut de descendance directe et légitime, la succession s'opère au profit des frères et soeurs du Prince régnant et de leurs descendants directs et légitimes, par ordre de primogéniture avec priorité masculine au même degré de parenté.
Si l'héritier qui aurait été appelé à monter sur le Trône en vertu des alinéas précédents est décédé ou a renoncé avant l'ouverture de la succession, la dévolution s'opère au profit de ses propres descendants directs et légitimes, selon l'ordre de primogéniture avec priorité masculine au même degré de parenté.
Si l'application des paragraphes ci-dessus ne permet pas de pourvoir à la vacance du Trône, la succession s'opère au profit d'un collatéral désigné par le Conseil de la Couronne sur avis conforme du Conseil de régence. Les pouvoirs princiers sont provisoirement exercés par le Conseil de régence.
La succession au Trône ne peut s'opérer qu'au profit d'une personne ayant la nationalité monégasque au jour de l'ouverture de la succession.
Les modalités d'application du présent article sont fixées, en tant que de besoin, par les statuts de la Famille Souveraine, pris par Ordonnance Souveraine.
The succession to the throne, opened by death or abdication, takes place direct and legitimate issue of the reigning prince, by order of primogeniture with priority given to males within the same degree of kinship.
In the absence of direct legitimate issue, the succession passes to the brothers and sisters of the reigning prince and their direct legitimate descendants, by order of primogeniture with priority given to males within the same degree of kinship.
If the heir who would have acceded by virtue of the preceding paragraphs is deceased or has renounced before the succession became open, the succession passes to his own direct legitimate descendants, by order of primogeniture with priority given to males within the same degree of kinship.
If the application of the preceding paragraphs does not fill the vacancy of the throne, the succession passes to a collateral appointed by the Crown Council upon same advice of the Regency Council. The powers of the prince are temporarily held by the Regency Council.
The throne can only pass to a person holding monegasque citizenship on the day the succession opens.
The procedures of application of this article are set, as needed, by the statutes of the Sovereign Family, promulgated by Sovereign ordinance.
From 1962 to 2002 article 10 read as follows:
La succession au trône, ouverte par suite de décès ou d’abdication, s’opère dans la descendance directe et légitime du Prince régnant, par ordre de primogéniture, avec priorité des descendants mâles au même degré de parenté. À défaut de descendant légitime, l’enfant adoptif ou ses propres descendants légitimes sont habiles à succéder. The succession to the throne, when opened by death or abdication, takes place within the direct and legitimate descent of the reigning Prince, by primogeniture, with precedence of males within the same degree of kinship. In the absence of a legitimate descendant, the adopted child or the legitimate descendants thereof are able to succeed. Article 16
Le Prince confère les ordres, titres et autres distinctions.
